Ok, I was on a page I probably shouldn't have been on and I clicked on a link to download. The download started and I realized it wasn't what I thought it was and cancelled the download almost immediately. Then things got weird: on the bottom right of my display the icon hiding function kept moving left and right and any button I pushed would just make another button activate(such as when I was scrambling to disable my net connection) and i particularly remember going to shut down the computer and pushing "turn off" but stand-by kept hilighting and then it just went into standby mode. Upon successfully restarting my computer a got about a zillion error-reporting things and the analyses ranged from a Mcaffee firewall error (which I uninstalled a long time ago) to a device driver error to I don't even know what else. It always said that the system had recovered from a serious error over and over again after each report was sent. Yikes that got me scared.
SO, I ran my virus scanner, deleted all my temp internet files, searched for new files created today, didn't find anything, ran system restore, the problem came back and when I undid the system restore things seem to be working fine now... but I'm worried. The download had barely begun?!?! It was like my desktop had been taken over or something, anyone heard of something like this before?
